cfg_rd
The cfg_rd command performs single-cycle PCI configuration read
transactions with the address provided in the command argument.
cfg_wr
The cfg_wr command performs single-cycle PCI configuration write
transactions with the address, data, and byte enable provided in the
command arguments.
mem_wr_32
The mem_wr_32 command performs a memory write with the address
and data provided in the command arguments. This command can
perform a single-cycle or burst 32-bit memory write depending on the
number of DWORDs provided in the command argument.
■
The mem_wr_32 command performs a single-cycle 32-bit memory
write if the DWORD value is 1.
